That single Saturday changed their lives forever. During the detention they discovered things about each other as well as themselves. As detention ended, the five of them knew they couldn't go back to the lives they had before. But as high school dictated, the group had to go their separate ways.
Before leaving the group made a pact. To make sure they didn't lose who they had become that day, they would guarantee themselves a detention, by whatever means necessary, twice a year. In the fall and again in the spring.
As for Richard Vernon, he couldn't care less. In his mind it was the perfect torture for these idiots.
For "The Breakfast Club", it was the perfect Saturday.
